60 years is three half life for the substance, so 40*1/2^3=5
The correct answer for this question is this: "Species diversity measures the number of species in the biosphere, while genetic diversity measures the variety of genes in the biosphere, including genetic variation within species."
<span>Species diversity and genetic diversity are different in terms of what the two terms measure.</span>
Answer:
Intermediate neuron
Explanation:
Interneurons are the "middle man", neither a sensory or motor nueron, that creates neurial circuits, connecting a broad class of neurons in the spinal cord and brain. They enable communication from motor and sensory neurons in the central nervous systems and are classified into two groups; relay and local interneurons. Through neurial circuits, the brain is able to manage and deal with complex stuff such as decision-making and learning.
Answer:
Blastocyst,Blastoderm
Explanation:
The blastula is made up of a hollow spherical layer of cells, referred to as the blastoderm which surrounds a yolk or fluid-filled space called the blastocele or blastocoel. In most mammals, including humans, the structure formed next is the blastocyst, a mass of inner cells that are distinct from the blastula
Answer:
Explanation:
We are asked to find the energy given mass, specific heat, and change in temperature. Therefore, we must use this formula;
The mass is 15 grams and the specific heat is 0.129 J/(g×°C). Let's calculate the change in temperature.
- ΔT= final temperature - initial temperature
- ΔT= 85 °C- 22°C = 63°C
Now we know all the values:
Substitue the values into the formula.
Multiply the first numbers together. The grams will cancel.
Multiply again, this time the degrees Celsius cancels.
<u>121.905 Joules</u> are required.
